摘要： A method for updating location of a user equipment in a cellular system is disclosed. The method comprises the user equipment receiving route update radius information 220. The user equipment further calculates a route update radius from the received route update radius information 230 by using a random number generated by the user equipment. The user equipment then transmits the calculated route update radius to a cellular network 240. Alternatively, the method comprises the cellular network receiving a route update message from a user equipment 420. The cellular network further calculates a route update radius 430 using a random number generated by the cellular network. The cellular network then unicasts the calculated route update radius to the user equipment 440.

摘要： The present invention is directed to a method that includes determining 302 a distribution of channel conditions across a plurality of physical resource blocks (PRBs) (202-206) and dividing (304) the distribution of channel conditions into a plurality of levels (208-226). The method also includes ordering (306) a ranking of each of the plurality of PRBs according to an instantaneous channel condition for each of the plurality of PRBs and selecting (308) one of the plurality of levels corresponding to an observed condition for each of the ranked plurality of PRBs. In addition, the method includes reporting (310) a mean value of the channel conditions across the plurality of PRBs and a bit value for the selected level for each of the ranked plurality of PRBs.
